loosing tire pressure

[Rollsey]

Hello all,

My edition 30 keeps loosing tire pressure in the offside front and I am at a loss to know why. It has had this problem since I bought it 18 months ago. First I thought it was a leaky valve so had that replaced, it still lost around 1.5 bar of pressure roughly every 30 days. I then had the tyre replaced with a Michelin pilot sport still the same problem. The wheel looks fine although it has been curbed a few times. One thing I did take note of was when the lad was repalcing my tyre and had the wheel on the balancing machine he told me that it had a slight buckle, it's not noticable when looking at it and the wheel has no dents in the rim like i said its just got some minor scrapes from curb grinding. Has anyone had the same problem? or do you have any thoughts on what could be going on?

If the wheel is buckled maybe there could be a fine crack allowing air out or maybe the tyre isn't sealing properly on the rim. Take the wheel off and squirt areas with a solution of washing up liquid and water and any leaks should soon show up as bubbles.

You just need to take it to a good tyre fitter to sort the puncture

Even a slightly buckled wheel will eventually lose pressure.

If none of the above work.....try a tube? Not brill, but what else can you do??

I had this with a customers car and foumd it to be a hair line crack causing the loss of pressure. Another customer had a leaking valve not fully screwed in.
Another had a buckled rim which leaked air from it every couple of days. maybe worth what was said above re fairy with water or similar I use wind screen wash  in a squirty bottle and you'll soon find the leak.
